501 There are two different types of booting firmware on Alphas: SRM,
502 which is command line driven, and ARC, which uses menus and arrow
503 keys. Details about the Linux/Alpha booting process are contained in
504 the Linux/Alpha FAQ, accessible on the WWW from
505 <http://www.alphalinux.org/>.
506
507 The usual way to load Linux on an Alpha machine is to use MILO
508 (a bootloader that lets you pass command line parameters to the
509 kernel just like lilo does for the x86 architecture) which can be
510 loaded either from ARC or can be installed directly as a permanent
511 firmware replacement from floppy (which requires changing a certain
512 jumper on the motherboard). If you want to do either of these, say N
513 here. If MILO doesn't work on your system (true for Jensen
514 motherboards), you can bypass it altogether and boot Linux directly
515 from an SRM console; say Y here in order to do that. Note that you
516 won't be able to boot from an IDE disk using SRM.
517
518 If unsure, say N.

538 machines, but will use only one CPU of a multiprocessor machine. If

541 will run faster if you say N here.

613 For example, if one wanted the option of printing verbose
614 machine checks, but wanted the default to be as if verbose
615 machine check printing was turned off, then one would choose
616 the printing mode to be 0. Then, upon reboot, one could add
617 the boot command line "verbose_mcheck=1" to get the normal
618 verbose machine check printing, or "verbose_mcheck=2" to get
619 the maximum information available.

642 SRM is something like a BIOS for Alpha machines. There are some
643 other such BIOSes, like AlphaBIOS, which this driver cannot
644 support (hey, that's not SRM!).
645
646 Despite the fact that this driver doesn't work on all Alphas (but
647 only on those which have SRM as their firmware), it's save to
648 build it even if your particular machine doesn't know about SRM
649 (or if you intend to compile a generic kernel). It will simply
650 not create those subdirectory in /proc (and give you some warning,
651 of course).
652
653 This driver is also available as a module and will be called
654 srm_env then.
